To all whom it'may concem: 4

Be it known that 1, PAUL WM". WERNER,

a citizen of the United States, residing at Niota, in the county of Hancock and State of Illinois, have invented a new and usefful Pencil, of which the following is a specification.

The device forming the subject matter of this application is a. magazine pencil, and one object of the invention is to provide novel means whereby the pencil may be assembled readily-and be taken apart with equal facility. Another object of the invention is so to construct the pencil that it will not tire the user when held in the hand. A

- further object of the invention is to provide novel means for advancing the lead and for holding the lead after the same has been advanced. v

In the accompanying drawings Figure 1 shows in longitudinal section,

a pencil constructed in accordance with the invention, parts appearing in elevation; re 2 is a cross section on the line 22 of igure 1; Figure 3 is a cross section on "the line 3-3 of Figure 1; Figure 4 is a cross section on the line 44 of Figure 1; Figure 5 is a cross section on the line 5--5 of Figure 1; and Figure 6 is a fragmental elevation showing-t e tip. The device forming the subject matter of. this ap lication includes a body, comprising a barre 1 which-may be made of hard rub- .ber if desired. At one end, the barrel 1 is supplied with internal threads 50. The numeral 2 marks a tip having a reduced neck 3 provided with threads 4 engaged with the threads of the barrel 1, the neck being received in the barrel. The neck 3 has oppositely disposed longitudinal grooves" or seats 5. On the inner end of the neck 3 is mounted a retainer 6 in the form of a disk, this element being made of metal, if desired, and having a polygonal opening 7,

which, preferably, is triangular in shape.

The disk or retainer 6 has springfingers 8 received in the grooves 5 of the neck 3 and constituting means for holding the retainer on the inner end of the neck. -A tubular liner 9 is disposed within the tip 2 and forms part thereof, the liner terminating in a conical point 10 which may be slit, as indicated at 51, to enhance the hold of the part 10 on the lead when the pencil is in use.

A rotatablemember is journaled in the barrel 1. The rotatable member 11 is a com- 1921. Serial a... 488,563.-

posite structure and 'includes a tubular element 12 having a reduced tubular foot 14 provided with internal threads 15. The rotatable member embodies a knob 16 reduced to form a stem 17,'the stem terminating in "a reduced portion 18. engaged within a thimble 19, an eraser 20 being inserted into the inner end of the thimble 19. The stem 170i theknob 16 and the thimble 19. fit tightly in the tubular element 12, the construction being such that when rotation is imparted to'the knob 16, rotation will be imparted likewise, to the member 11. A reserve supply ofleads may be carried in the tubular member 12, the knob 16 and parts carried thereby constituting a closure end that the eraser 20 may be used.

An inner abutment 21 is secured to the foot 14 of the rotatable member. An outer abutment 22 is likewisesecured 'to the foot 14. Between the abutments 21 and 22"is'f80 located a bearing 23 wherein the foot 14 of the member 11 is rotatable. Inits outer end, 6 the bearing 23 has kerfs 24 so that a prop-' erly shaped tool can be inserted'into the I kerfs 24, thereby to advancei the bearing 23 into the barrel 1 until the bearing arrives at the inner end of the threads 50lin the barrel, it being understood that the bearing 23-.is threaded into the. barrel. -The construction above described obviously facili-" ta-tes greatly the assembling of the pencil.

The pencil includes a plunger embodying a head 26 located within the reduced tubular foot 14 of the rotatable member H: and engaged with the threads 15 thereof, the plunger including a reduced stem 27 projectin'g from the head. The stem 27 preferably is triangular in cross section and is slidable in .the bore of the liner ,9. a The stem 27 is received in the triangular open- 0 ing'7 of the retainer 6 and is heldtherein against rotation. v

When-rotation is imparted to the member 11 by means of the knob-16,.the plun er .2627 V will beadvanced, because the lies. 26

liner 9, the tip 2 being peculiarly efficient in which'grip and hold the lead.

I claim I In a device of the class described, a body;

a rotatable member journaled in the body; a bearing threaded into the body; the hearing having a kerf; the rotatable member being j ournaled in the bearing; an abutment on the rotatable member and coacting with the bearing, the abutment being cut away threaded connection with the rotatable memher; and means for holding the plunger against rotation. V y

In testimony that I claim'the foregoing as my own, I have heretoafiixed my signature in the presence of two witnesses.
